CD34 Antibodies
Cluster of differentiation 34 (CD34) is a transmembrane phosphoglycoprotein that is a surface marker for hematopoietic stem cells and progenitor cells. The canonical human CD34 protein isoform is 385 amino acids (aa) in length with a calculated theoretical molecular weight of 40 kDa and an observed molecular weight of ~115 kDa. We offer multiple CD34 antibodies that have been featured in 60+ publications, many with 4- and 5-star customer reviews. Search our extensive category for recombinant monoclonal antibodies, monoclonal antibodies, polyclonal antibodies, and CD34-conjugated antibodies. Validated research applications for our CD34-antibodies include CyTOF-ready, ELISA, Flow Cytometry, ICC, Immunofluorescence, IHC-Frozen, IHC-Paraffin, Immunoprecipitation, and Western Blot. These CD34 antibodies are reactive in Human, Rat, Mouse, Canine, Porcine, and many more. View the technical details, images, references, reviews, and related products to help choose the anti-CD34 antibody best suited for your research needs. Each CD34 antibody is fully covered by Novus’ Guarantee+.
